I plan to spray everything but the car's exterior in 3 - 4 coats of custom mixed ~25% Grey SPI epoxy, for visibility reasons, since I am visually impaired and night blind. The exterior will be Black SPI epoxy for sanding contrast. This is on an air-cooled VW and I plan to paint the chassis/pans and suspension in the same Grey. The car will not be completed for a few years....Epoxy only will be the most chip resistant, and probably the most chemical resistant as well, once full cure is achieved.
Will SPI epoxy that cures for 2 -3 years be rugged enough to stand up to the underside and wheel well abuse? If not, what would be a suitable and durable topcoat, other than a tintable bedliner, that can be had in a light color?
Cheers,
Emil
